Unfortunately, this actually touched the file pointed to by the symlink,
if you stat the symlink you will see that mtime did not change.

Actually, this would not have followed the symlinks so it does the same
thing as before.  I think it is actually hard (or not possible) to
change mtime on symlinks under Linux.

If /var is on the same filesystem, you could use hard links instead of
symlinks.  Otherwise I would just add the appropriate ln -sf in the hook
before notmuch new.

The real solution is for notmuch to check mtime of whatever the
symlink's target.
